The mining and mineral processing industries, due to their harsh environments, demand high-performance bearings. These machines are diverse, ranging from mineral crushers to cutting, screening, loading, and conveying equipment, all operating continuously 24 hours a day. A failure in any of these machines can significantly impact production at the mining site.
Due to the varying operating environments, bearing designs must meet specific requirements. Reliability, durability, and high productivity are crucial characteristics for this industry.
EISENBERG bearings offer the following advantages:
High operational safety and stability
High load capacity
Low maintenance requirements
Resistant to shock and vibration
Simplified installation and disassembly
Specialized solutions: Under these harsh operating conditions, the use of self-aligning roller bearings and cylindrical roller bearings reduces maintenance costs and downtime.
The following are typical examples of equipment in the mineral processing and mining industries that use EISENBERG bearings:
Roller Presses
Roller presses are used in the cement industry, as well as in the processing of industrial minerals and coal. Roller presses operate under extremely heavy loads, low speeds, and contaminated environments. EISENBERG spherical roller bearings, with their design and lubrication principles, play a crucial role in roller press applications. They significantly reduce maintenance costs and downtime.
Grinding Mills
Grinding mills are used to crush mineral raw materials and operate in extremely harsh environments. The pinion shafts and trunnion bearings face challenges from extreme temperatures, heavy loads, and contaminants, impacting equipment efficiency. As grinding mills are critical processing equipment, overcoming these challenges is essential to ensure their proper and efficient operation.
Crushers
There are four main types of crushers: jaw crushers, cone crushers, rotary crushers, and impact crushers. Each type has unique characteristics, using different bearings and sealing devices, and requiring specific lubrication methods.
Crusher operating environments are dusty, hot, and often humid. Crusher operating conditions are very demanding, frequently subjected to impacts and heavy loads. EISENBERG offers solutions for each crusher type.
Conveyors
Conveyors transport ore from one processing unit to another. Conveyors play a vital role in mining and ore handling processes. However, conveyors are constantly subjected to heavy loads and impacts, and often operate in harsh environments, making downtime very common. Therefore, conveyor performance is often a primary consideration in mining and ore handling.
EISENBERG spherical roller bearings are designed for harsh operating environments and compensate for eccentricity and shaft deflection. Specially developed cylindrical roller bearings are used for hub deployment non-drive pulleys.
